"Site multihoming" to one provider (called site multiconnecting in the v4 
draft) is basically a no-brainer, AFAIK.  Is there something here which 
leads you to believe we need to work on this?

We could push multi-connecting as a solution/workaround for some use cases 
though.  IMO, that makes perfect sense to me, but at the same time, it 
cannot meet *all* the sites' needs, so we need something else too.
